Abstract：An energy-balanced connected coverage model is proposed for solve the problems that limited energy of sensor nodes and imbalanced energy consumption of minimal connected cover methods make against the lifespan of wireless sensor networks. The model uses Voronoi diagram and Delaunay tessellation to partition wireless sensor network and to distinguish the redundancy nodes overlapping target region, uses hop to sink node to stratify nodes. And then, a method to choose closeable nodes is introduced. The simulation results indicate that the network educed by the non-minimal connected cover set constructed by the model can balance the node energy consumption, use optimized route and weaken the influence of the key points on route.
